 The types of paints are broadly classified into phenolic paints, alkyd paints, polyurethane paints, nitrocellulose paints, polyester paints (PE paints) and PU paints. Among them, phenolic paint and alkyd paint are basically eliminated in the decoration due to the poor texture and adhesion of the paint film, and a large amount of nitrocellulose paint, polyester paint and PU paint are used.

Due to the simple construction and suitable for manual operation, the nitrocellulose lacquer is used by most hand-decorated woods, so the paint film is thin, the hand feel is not good, and the effect is not satisfactory. The advantage of PU paint is that it is easy to be sanded, and the processing process saves time and effort. The disadvantage is that the paint film is soft, and the slight bump is easy to produce white shadow dents. If at least one layer of PE paint is in the paint layer, this possibility is greatly reduced. The advantage of PE paint (polyester paint) is that the paint film is hard, the hiding power is strong, the transparency is good, and the veneer texture can be better expressed. The disadvantage is that it is difficult to polish, and the processing process is time-consuming and laborious. Most manufacturers are not willing to use PE coating.
At present, 90% of the wooden doors on the market use polyester paint, and a few manufacturers use PU paint. In general, polyester paints and PU paints have to go through six processes, such as color finding, three bottoms and two sides. Some brands increase the curing and waxing process.
Therefore, paint is one of the factors that must be considered when choosing a wooden door. It directly affects the texture and feel.
